My husband brought my 4 year old daughter to the tour. She was very excited with the whole thing. However upon ending the tour, she was very sad and told me she didnt get a whistle. I asked my husband what happened, he said all the kids in the tour (3 kids) got it except her because they only have 3 whistles to be given away. Oh come on the whistle didnt cost much right? For a little kid it means a lot even though its not valuable. I don't understand it at all why can't they just spare some for kids on the tour. The duck tour in Singapore had a duck whistle given to all of its passengers!!!
